• What is the cause and solution for SAP error message RSTRAN669 - Field &1 does not exist in new source ?

  The SAP error message RSTRAN669, which states "Field &1 does not exist in new source," typically occurs during the process of data transfer or transformation in SAP BW (Business Warehouse) when there is a mismatch between the fields in the source and the target data structures. This error can arise in various scenarios, such as during data loading, transformation, or when working with InfoObjects.
  Cause:
  
  
  Field Mismatch: The field specified in the error message (&1) does not exist in the new source structure. This can happen if:
  
  The source data structure has been changed (e.g., fields added, removed, or renamed).
  The InfoSource or DataSource has been modified, and the transformation rules have not been updated accordingly.
  The data model has been altered, leading to discrepancies between the source and target.
  
  
  
  Transformation Issues: If you are using a transformation to map fields from the source to the target, the transformation may reference a field that no longer exists in the new source.
  
  
  DataSource Changes: If the DataSource has been changed (e.g., a new version of a DataSource is being used), it may not contain the same fields as the previous version.
  
  
  Solution:
  
  
  Check DataSource and InfoSource: Verify the structure of the DataSource and InfoSource to ensure that the field in question exists. You can do this by:
  
  Navigating to the DataSource in the SAP BW system and checking its structure.
  Comparing the old and new versions of the DataSource to identify any changes.
  
  
  
  Update Transformations: If the transformation is referencing a field that no longer exists, you will need to:
  
  Open the transformation in the SAP BW system.
  Update the mapping to reflect the current structure of the DataSource.
  Remove or replace any references to the missing field.
  
  
  
  Adjust InfoObjects: If the field is an InfoObject, ensure that it is correctly defined and available in the target InfoProvider. If it has been deleted or renamed, you may need to adjust your data model accordingly.
  
  
  Re-activate Objects: After making changes, you may need to re-activate the transformation, DataSource, or InfoProvider to ensure that the changes take effect.
  
  
  Test Data Load: After making the necessary adjustments, perform a test data load to ensure that the error has been resolved.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (Data Warehousing Workbench) to access InfoProviders, DataSources, and transformations.
  Change Logs: Check the change logs for the DataSource or InfoSource to see what modifications have been made recently.
  Documentation: Review any documentation related to the changes made to the DataSource or InfoSource to understand the impact on existing transformations.
  
  By following these steps, you should be able to resolve the RSTRAN669 error and ensure that your data transfer processes function correctly.
